Anti-marking Pen Fouling Properties
Drawing a line with an oil-based pen and leaving it for 3 hours. Evaluate if the line can be wiped off with BENCOT M-3II (made by Asahi Kasei Corporation) soaked in a mixture of ethanol and toluene (1:1)
Compared to the blank, it can be seen that the addition of X-48-1801 sufficiently wipes off the line.
Substrate: glass
Weather Resistance
Accelerated weathering tests were conducted using a super accelerated weathering tester (Eye Super UV Tester SUV-W151 made by Iwasaki Electric Co., Ltd.).
A polyester coated steel sheet was used as the test specimen, and the gloss and color difference of the coating film were evaluated after the test.
As the X-48-1801 content increases, the gloss retention rate increases and the yellowing is suppressed.
*1 cycle: 4 hours of UV (90mW) irradiation -> 4 hours of darkness -> 4 hours of condensation
Frequently Asked Questions
| Question: About X-48-1801 | Answer |
|---|---|
| 1. What is X-48-1801? | It is a silicone oligomer with an isocyanate (NCO) in its molecule. |
| 2. How to use? | It can be used as a curing agent for various polyol resins. It is characterized by low yellowing and can be cold blended to provide durability and water repellency. We introduce the method of cold blend for two component acrylic urethane in Paint Formulation Example. |
| 3. Can it be used alone as a urethane curing agent? | It is recommended to use it as an auxiliary agent to the curing agent, as it will not provide a sufficient cross-linked coating by itself. |
| 4. What should I do for the actual formulation? | Please refer to the Paint Formulation Example on this web page. |
| 5. Does X-48-1801 compatible with isocyanate curing agent? | Yes, it is compatible. |
| 6. How stable is the product in blends with isocyanate curing agents? | It can be stored in a cool and dark place (below 25℃ and out of direct sunlight) with a tight seal to prevent moisture and humidity from entering the product and keep it relatively stable. |
| 7. Is it water repellent? | It has water repellency, although it is slightly inferior to silicone fluid. |
| 8. What should I do if the water repellency is insufficient? | It is possible to improve the water repellency by adding 1000ppm to several percent of carbinol-modified fluorine-containing silicone, or modified silicone fluid.。 |
| 9. What are the possibilities and effects of using it as a resin modifier? | Modification of active hydrogen (-CH2OH, -NH2, -SH, etc.) in resins can provide durability, heat resistance, and water repellency. For more information, please contact our sales department. |
| Question: About compatibility | Answer |
| 1. What are the acrylic polyol resins that are easily compatible? | Silicone modified resins are easily compatible, and even unmodified resins can be used to the extent that they are compatible. |
| 2. What about compatibility with polyols other than acrylics? | Alkyd polyols, polyester polyols and epoxy resins tend to be less compatible than acrylic polyols, but they may be compatible. |
| 3. What about compatibility with fluorinated polyols? | Not confirmed. |
| Question: About formulation | Answer |
| 1. In the paint formulation example, pigments are used, but what is the recommended formulation for clear color paints? | ① 0.75 x (OHV of polyol)/(NCO% of X-48-1801) g of X-48-1801 per 100 g of polyol, and 6.74 x (OHV of polyol)/(NCO% of curing agent) g of curing agent. The content of X-48-1801 is about 30 wt% (solid content ratio). ② 0.22 x (OHV of polyol)/(NCO% of X-48-1801) g of X-48-1801 per 100 g of polyol, and 7.27 x (OHV of polyol)/(NCO% of curing agent) g of curing agent. For both ① and ②, please add 0.25wt% catalyst per total solids content. |
| 2. What is the functional group equivalent ratio of the formulation described in the answer to question 1 above? | Similar to the paint formulation example on this webpage, the polyol OH/curing agent NCO/X-48-1801NCO = 1.0/0.9/0.1 (equivalent ratio) and 1.0/0.97/0.03, for an overall OH/NCO equivalent ratio of 1.0. |
| 3. Is it possible to increase the amount of X-48-1801 in the formula? | It is possible to use polyol OH/curing agent NCO/X-48-1801NCO = 1.0/0.80/0.2 (equivalent ratio) or higher if there is compatibility. |
| 4. What will be changed by increasing X-48-1801? | The more it is increased, the better the weather resistance, heat resistance and anti-marking pen fouling properties. |
| 5. What is the minimum amount for X-48-1801 to be effective? | Polyol OH/curing agent NCO/X-48-1801NCO = 1.0/0.97/0.03. The minimum amount varies depending on the polyol and curing agent. |
| 6. Should the amount of X-48-1801 be determined by equivalent ratio? | Since the amount of X-48-1801 varies depending on the number of functional groups of the polyol and curing agent used, the amount of X-48-1801 should be determined by equivalent ratio. |
| 7. What is the recommended NCO / OH equivalent ratio? | We recommend NCO / OH = 1.1 to 0.9. |
| 8. What is the recommended dilution solvent? | Single or mixed solvents such as butyl acetate, ethyl acetate, MEK, MIBK, toluene, and xylene. Alcohols and glycol ethers with hydroxyl groups are not recommended. |
| 9. What if I don’t want to use a urethanation catalyst? | Curing time and pot life will be delayed. |
| 10. How can I speed up the curing process without using a urethane catalyst? | We recommend heat curing at 80°C for 15-20 minutes. |
| 11. What if uncured components remain on the surface of the cured film? | It is possible that the catalyst amount for urethanization is too high. The problem may be solved by reducing the amount of catalyst. In addition, forced drying by heating tends to cause such a phenomenon, and it may be solved by curing at room temperature. |
| 12. What non-organotin catalysts can be recommended? | Metal complexes such as bismuth carboxylate and zirconium are recommended. For more information, please contact our sales department. |
| 13. How to delay the Pot life? | We recommend reducing the amount of catalyst. The recommended amount is 1/3 to 1/2 of the amount of catalyst in the Paint Formulation Example. |
| Question: Isocyanate curing agent to be used together | Answer |
| 1. How to develop durability? | Non-yellowing HDI Nurate (Paint Formulation Example) or HDI Adduct is recommended. |
| 2. How to obtain high hardness? | IPDI Nurate or IPDI Adduct is recommended. |
| 3. How to get flexibility? | HDI Nurate (same as Paint Formulation Example) or HDI Adduct is recommended. |
| 4. How to increase solid contents of paints in the same viscosity? | HDI Nurate (Paint Formulation Example) is recommended. |
| 5. What if stain resistance is important for indoor use? | Yellowing TDI Adduct is recommended. |
| 6. What is the importance of non-yellowing for indoor use? | Non-yellowing IPDI Nurate or IPDI Adduct or XDI adduct is recommended. |
| 7. What about use for rigid polyurethane? | It is probably possible to use our products in rigid polyurethane. Shin-Etsu have not evaluated it ourselves, so we would be happy to evaluate it with samples. Please contact our sales department to request a sample. |
| 8. What about the use for elastomers? | This oligomer does not contain any solvent and can be applied to elastomers. |
| 9. What about applications other than urethane? | It can be applied to thiourethanes as well as urethanes. |
| Question: About applying | Answer |
| 1. What are the drying conditions? | Dry at room temperature (20℃~25℃) for 1 week. Or, forced drying (80℃ x 20 minutes) + 1 day of drying at room temperature is the standard. |
| 2. What kind of coating methods are available? | Please follow the normal methods such as spraying and roll coater. |
| 3. What precautions should I take when applying? | The paint will thicken with time and eventually gel and solidify. Please use up the paint within the usable viscosity range. |
| 4. What is the film thickness? | Not specific, but in the range of 5μm~100μm. |
| 5. What substrates can be coated? | Metals, non-ferrous metals, glass, inorganic materials, plastics, and wood. The surface of the base material should be degreased or otherwise cleaned before application. |
| 6. How do I ensure adhesion to the substrate or the base coat? | It is recommended that X-48-1801 be mixed with 1.1 to 1.2 NCO / OH equivalents of the total paint. |
