Description:
The series of silicone rubber is divided into dispensing type SB4135. They can not only be fabricated into trademarks independently, but also be fabricated into trademarks through cloth pressing and leather pressing.
SB4135 dispensing type trademark silicone rubber belongs to liquid addition cure system. The amount of the curing agent can be 10% and can also be adjusted to the mixing proportion of 10 : 1. The curing agent is two-component high-strength liquid silicone rubber made of basic compound, cross-linking agent, catalyst, padding and additive. Those materials do not contain heavy metal and aroma solvent, hence, it's not harmful to human body.
Typical curing Condition:
170℃×5mins, prolong or shorten the curing time appropriately according to the thickness and size of the product during actual use.
Using Instructions:
The mixing proportion of SB4135 is 10:1. Mix component A and component B sufficiently and evenly according to the mixing proportion before use. The process of vacuum-pumping is also needed.
Note:
The series of products must not be in contact with organisms like N, P, S, etc., ionic compounds like Hg, Bi, As, etc., and alkynes, vinyl compounds, etc. to avoid the situation at the products can not be cured due to platinum catalyst poisoning. The products particularly can not be in contact with PVC which contains lead causing catalyst poisoning. Some organic pigment also can slow down the curing time or cause uncured .
After SB4135 are mixed, the silicone rubber must be used up within 4 hours, otherwise the cross-linking and curing arises to lose effectiveness. In case of a higher surrounding temperature, more attention should be paid.

Package:
General packages of SB4135 products is in 5kg per can, 20kg per pail and 200kg per barrel.
Precautions:
The products can be transported as safety and non-hazardous goods since they are noninflammable with resistance to a high temperature above 300℃.
