ELASTOSIL® 9100 P

ELASTOSIL® 9100 P is a one-part, neutral-curing, low modulus silicone sealant with very good adhesion and shelf life for DIY applications.

ELASTOSIL® 9100 P cures at room temperature in the presence of atmospheric moisture to give a permanently flexible silicone rubber.

Processing

The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and a clean, lint-free, cotton cloth. Remove residual solvent before it evaporate with a fresh clean, dry cloth.

It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coating materials (paints, varnishes and glazes) or organic plasticizer containing rubbers (EPDM, butyl and neoprene) can lead to discoloration or other impairments like loss of adhesion of the sealant. Materials in direct contact with the applied sealant like cleaning agents and materials in indirect contact like gaseous emissions can damage the sealant in its function or change its appearance. Because of the multitude of these materials, Wacker cannot make a general statement to the compatibility of materials with the sealant. In case of doubt the user shall conduct appropriate preliminary tests.

The time until complete curing may be extended at lower temperature, lower humidity, increasing film thickness or by low volume of air exchange.

The use of tooling agents should be avoided if possible. Otherwise, water or a diluted solution of a little neutral soap or alcohol in water should be sparingly applied

The work should only be carried out with sufficient fresh air supply. Wear appropriate protective clothing when processing.

Adhesion

ELASTOSIL® 9100 P exhibits good primerless adhesion to most of the substrates used in DIY-applications, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker, metals e.g. aluminium, steel, zinc or copper.

Users must carry out their own tests due to the great variety of substances. The adhesion can be improved in many cases by pretreatment of the substrates with a primer. If adhesion difficulties arise please contact our technical service.
