[performance characteristics].
DY-101 glass resin is an ethanol solution of silicone prepolymer. The main component structure is:
[CH3 (C2H5O) 2 sio0. 5]. [CH3 (OH) 2 sio0. 5]. [CH3 (OH) (C2H5O) SiO0.5]
. [CH3 (C2H5O) the SiO]. [CH3 (OH) the SiO]. [CH3SiO1. 5)
This product after curing hard transparent film, insulation performance is good, and the friction resistance, heat resistance, ageing resistance, radiation resistance, low temperature embrittlement, hydrophobic, moisture-proof, non-toxic, light transmittance strong advantages. This product is low temperature curing, soluble in ethanol, butanol, amyl alcohol, ethyl acetate, acetone and other solvents.

[usage]
1, coated organic material such as glass, polycarbonate, can improve the light transmittance, wear resistance and resistance to ultraviolet radiation, suggested that as the plane glass, automotive glass, sunglasses, optical instruments, electronic instrument display and the surface of the protective film.
2. Coated copper, aluminum and other metal components can be effectively anti-corrosion.
3. As a gloss coating for paper and ceramics (such as poker, trademark, book cover, etc.), it can make it smooth, wear-resistant and waterproof, and increase elasticity and flexure.
4. Insulation coatings for electronic and electrical components under high temperature and high humidity conditions.
5. Replace the emulsion paint for the interior wall of the advanced decorative paint, smooth wear-resisting, long life.
6. Surface treatment of silicone rubber bonded to metal surface at room temperature.
7. Other applications that are not fully developed.
[usage and dosage].
Dilute 1 ~ 10 times with alcohol, and then apply appropriate coating on the substrate surface, normal temperature or heat curing. In order to achieve rapid curing of normal temperature, the product is equipped with a set of curing agent, and the dosage of curing agent generally accounts for 0.1~1% of the total diluted solution.
[precautions].
DY-101 is a flammable product, and the risk is similar to that of anhydrous alcohol. Light, heat, air, acid, alkali and other things will accelerate polymerization, should be stored in dark and low temperature, stored at room temperature for no more than 3 months. After adding curing agent solution should be finished as soon as possible, in order to avoid failure, if not immediately run out, can add hardener 1.6 times weight of ice acetic acid as inhibitor, can prolong operation time 8 ~ 12 hours after China's entry into wto. In addition, adding 1~2% of DBP or polyether modified silicone oil can increase the flexibility of the film.
