Description:
LSR-3019 is two component RTV addition/platinum cure type transparent silicone rubber compounds for mold making. The two component system consists of a base (Part A) and curing agent/catalyst (Part B). After mixing parts 'A' and 'B' in the correct proportions, the system will cure at ambient temperatures within 24 hours by an addition reaction, and the rate of cure can be accelerated by heat. The cured rubber exhibits excellent physical and electrical properties.
Applications:
LSR-3019 is suitable for applications where very accurate dimensional reproduction is required. (Such us rapid prototyping, jewelry or model making where model visibility is important, it produces exactitude molds of complicated parts, precisely reproducing the dimensions of the original. ) And also where higher temperature tolerance is required or where the maximum of repetitive releases will be possible.
Can be used for casting a range of materials, plaster, polyurethane, polyester and other reactive resins, concrete are the materials typically used.
Features:
Addition cure silicone rubber is a more advanced type of RTV silicone than the more cost effective "condensation cure" silicone. It has many merits, such us:
High dimensional stability
Very low shrinkage - less than 0.1%
Fine detail reproduction
Transparent
High tear and tensile strength
Curing accelerated by heat
High chemical resistance (PU)
