Sika AG, a globally integrated company supplying specialty chemicals and application knowledge has launched a new PV potting agent ‘Sikasil’ AS-787 SL. The new two-component silicone potting agent is claimed to offer a fast curing time that enables shorter cycle times and a high automation index for junction box potting for crystalline and thin film photovoltaic technologies.

Problem

Excellent adhesion of the PV module junction box is required for longevity and safety. However, shorter assembly times are required to reduce manufacturing costs.

Solution

The Sikasil AS-787 SL features, despite the excellent flowing behaviour, a very short non-flow time to shorten and secure the storing time before handling and packaging. Due to the two component technology the fast and uniform curing is independent from humidity and can even be accelerated by slight heating, while maintaining required long-term weatherability and adhesion to backsheet materials and glass.

Applications

Used for potting and sealing of the junction boxes of photovoltaic modules 

Platform

Sikasil AS-787 SL is claimed to offer a balance of raw materials that negates sedimentation occurring and therefore no mixing is needed prior to usage, compared with other potting materials. The material (Colours are black and white) can be applied with most of the common dispensing systems for potting materials. With a UL 94 V-0 certification the product meets the highest flammability rating.

Availability

July 2012 onwards.
