Kömmerling has launched its new butyl based framing sealant ‘HelioSeal’ PVS 120. In contrast to existing framing sealants on the market HelioSeal PVS 120 is claimed to provide immediate green strength and superior water and moisture vapour tightness, while being hot applied and able to be used by hand or in fully automated high speed production lines.

Problem

Crystalline PV module makers as well as those in the thin-film industry know that water tightness alone is not enough for the protection of PV modules. It is also necessary to ensure moisture vapour tightness of the whole system especially in the framing area a parameter for durability. The PV industry is looking for sealing systems which can be easily used in the production process (e.g. one component, no mixing, fast curing, less waste).

Solution

HelioSeal PVS 120 is a butyl rubber-based hot melt framing sealant which is delivered ready to use. Easy handling means simple processing by using pail or drum melting equipment and minimal waste. Along with a high level of green strength, superior water and moisture vapour tightness (less than 0.2 g/m2d) is another main feature. Primerless adhesion to glass, aluminium, galvanized and stainless steel are other valuable features.

Application

Long life sealant for ultra secure framing of thin film and crystalline PV modules

Platform

HelioSeal PVS 120 can be supplied for automated application equipment from 20 litre pails to 200 litre drums for easy integration in production lines. HelioSeal PVS products are used for sealing both the inner and outer components of modules with ease and the confidence of long term durability with high resistance to aging and stresses.
