What are the common curing agents for silicone resins

Nov 29, 2019

    Silicone resins have long-temperature self-drying type and high-temperature curing type. To accelerate curing, a small amount of diethylenetriamine or triethylenetetramine can be added. The paint film gradually hardens even if it begins to cure. The amount of dry agent is very small, it is best to determine its amount through practice. High temperature curing generally volatilizes the solvent at a lower temperature, then dries at 160-180 degrees, and finally cures at 220 high temperatures. Polyorganosiloxane with a highly crosslinked network structure, usually using methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylphenyldichloro Various mixtures of silanes are hydrolyzed at lower temperatures in the presence of organic solvents such as toluene to obtain acidic hydrolysates. The initial product of the hydrolysis is a mixture of cyclic, linear, and crosslinked polymers, and usually also contains considerable hydroxyl groups. The hydrolysate is washed with water to remove the acid, the neutral primary polycondensate is thermally oxidized in the air or is further polycondensed in the presence of a catalyst, and finally forms a highly cross-linked three-dimensional network structure.

    It can have high-gloss, smooth, wear-resistant, waterproof, anti-aging properties. Suggested process: This product is a single component, and the thickness of the coating film can be adjusted with anhydrous methanol, ethanol, butanol as the diluent. Can be dip-coated, brush-coated, spray-coated, spray-coated. Then leave it at room temperature for 1 to 1.5 hours (humidity range 40% to 80%). Packaging, storage and transportation: 190 kg plastic barrels, stored in a dry, cool, ventilated place, and sealed. It is strictly forbidden from contact with water and air, waterproof, sun protection, fire prevention.
