RTV-2 Addition cure silicone rubber for concrete mold making supplier

Description

RTV-2 Addition cure silicone rubber for concrete mold making are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1. 

Main application

· Concrete mold
· GRC and Concrete moulding 
· PU resin casting
· General Mouldmaking
· Superior manual mold design

Main properties

· almost nil shrinkage
· high chemical resistance to aggressive components of some types of resins
· good tear strength (this feature ensures higher resistance to wearing and shearing) 
· high degree of precision in reproduction 
· high dimensional stability over time and  non-deformability 
· high resistance to high temperatures and ageing (resit to -60-200°C)
· excellent non-stick effect 
· environmental, odorless and nontoxic

Operation way

Step One: Take 100g of part A and add 100g of part B and mix the silicon rubber and the curing agent evenly.

Step Two: vacuum pumping

Without exception, this takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step Three: Brushing cast & Perfusion Molding operation.
