Acrylic Acid Modified Organic Silicone Resin SH-024

Performance and Usage

This product is produced from silanol which is hydrolyzed from phenyl monomer, methyl monomer and special acrylic monomers by specific process.

It has the advantages of both acrylic resin and silicone resin, such as good heat resistance, anticorrosive properties, strong adhesion and good gloss. It can be solidified at low temperature. It is suitable for the preparation of various series of high temperature resistant coatings, weather resistant coatings and H grade organic silicon insulating paint.

Construction reference

1.It can be cured at room temperature with two components, combined with isocyanate curing agent such as Bayer 3390, N75, etc ,the addition amount is 10 ~ 20% of the total resin.

2.High temperature curing, heating up to 180℃ for one hour curing. It can also cooperate with amino resin to shorten curing time.

3.This product contains toluenexylene and other flammable and explosive solvents. Attention should be paid to enhancing site ventilation during processing. Pay attention to fire prevention, anti-static, strictly cut off fire sources. Operators should pay attention to labor protection.
