SD-PG20

SD-PG20 is a 2 part addition cure silicone. For easy application the product was designed with very low viscosity.

It cure at room temperature but it is possible to accelerate the speed by heat. This product has anti-toxic

property, low viscosity, good fluidity, low shrinkage after curing, and excellent flame-resistance, thermal conductivity and electrical insulation properties.

Features and Benefits

• Thermal conductivity: 2.0 W/m·K
• Two-component, room or elevated temperature curing system silicone
• Low viscosity and high flow
• Excellent low and high temperature mechanical and chemical stability

Directions for Use

Oven atmosphere: nitrogen (recommended) or air;

The existence of some substances could inhibit or influence curing:

Organic tin and other metal compounds;

Silicone rubber containing tin catalyst; Sulfur, sulfur compounds, polysulfone compounds or other sulfur-containing compounds; Amine, polyurethane rubber or other ammonia containing substances; Phosphorus containing substances; Unsaturated hydrocarbon plasticizers; Flux residues, etc.

Clean the surface of pasted object to get rid of oil, water, dust, and other impurities;

Weight Part A and Part B accurately;

Blend: Mix the Part A and Part B evenly, using vacuum degassing if necessary.

(Some sediment maybe exist in the bottom of Part A or Part B. Please stir evenly before mixing.)

Pouring: Mixture should be used up within the working time, otherwise its viscosity will increase leading to it not suitable for pouring.
