INTRODUCTION
Two component room temperature poly addition curing fluid compound which cures with low shrinkage to a strong flexible mould rubber, it has high temperature and chemcal resistance making it well suited for reducing models with undercuts in polyurethane and epoxy resins..
Main field of application
Vacuum casting Rapid prototyping
Electrical application
Mould making
Special Characteristics:
Different Shore A Hardness available from 28-45
Fast and non shrink cure at room temperature which could can be accelerate considerable by the application of heat
Good transparency of the cured rubber
High tear strength
reproduce finite details from patterns
TECHNICAL PROPERTIES
Appearance (component A) : Translucent Component B (Hardener): clear liquid
Viscosity (cps) : 85000(at +23�C) 800
Mixing ratio (mould rubber Harder) : 10: 1 parts in weight
Work Time (at + 23�C) : 60 to 90 minutes
Demoulding time (at +23�C) : 20 to 24 hours
Specific gravity : 1.220 (at + 23�C))
Hardness (Shore A) at 2mm cured : 40
Tensile Strength kg/cm� (MPA) : 10
Tear strength kgf / cm (KN/M) : 14
Higher temperature and humidity will increase the cure rates and, therefore, reduce work time, lower temperature or humidity will slow the cure time. in standard cured time, the demolding time is 12-24hours. The mold can be used after 48 hours of cure
