LOCTITE® SI 5710 is a highly transparent silicone adhesive with polyaddition technology. It rapidly cures at room temperature with a rapid fixture time that can be accelerated by heat.
LOCTITE® SI 5710 is an efficient adhesive technology with a polyaddition enhanced silicone for enhanced stability under UV, high temperature, and increased humidity conditions. It consists of a two-component formulation to be mixed at a 1:1 ratio to form a low-viscosity, non-corrosive silicone adhesive that cures at room temperature to form an ultra-clear bond that releases no by-products and exhibits low shrinkage. Its cure can be accelerated by heat for time-sensitive potting applications in the lighting, electrical, and optical industries.
