Description
DOWSIL™ PR-1200 Primer is a one-component, clear, dilute solution of silane coupling agents designed to enhance adhesion of room-temperature and heat-cure silicones. The primer promotes bonding to a wide range of surfaces, including glass, plastics, metals, ceramics, and masonry materials. This general-purpose primer supports applications involving silicone elastomers and RTVs. It is supplied in a 2.9 kg pail and typically ships within 1–2 business days. Tiered pricing is available for multi-unit purchases.

FAQs

What is DOWSIL PR-1200 Primer, and what does it do?

DOWSIL PR-1200 is a one-component clear primer composed of dilute silane coupling agents dispersed in solvent. It enhances adhesion of room-temperature- and heat-cure silicone sealants and elastomers to substrates like glass, metals, ceramics, plastic, and masonry.

Which surfaces are compatible and how should it be applied?

Compatible with metals, glass, masonry, ceramics, and some plastics, including structural plastics. Surfaces should be clean, degreased, and possibly abraded. Apply a thin uniform coat by wiping, spraying, or dipping. Excess primer should be wiped away to avoid residue.

What are the typical performance properties and limitations?

Typical non-volatile content is ~4.9 %. Adhesion (180° peel) on aluminum is ~37 ppi (~25.5 N/cm²). Shelf-life at 35 °C is ~18 months. Curing depends on ambient moisture; low humidity or temperature may extend drying. Avoid curing beyond ~60 °C.

How should the product be stored and handled?

Store in tightly sealed containers below ~90 °F (32 °C) in a dry warehouse suitable for flammable materials (solvent-based). Avoid moisture ingress; a milky appearance indicates contamination and reduced performance.

Can this primer be used for medical or pharmaceutical devices?

No, this product is not designed or tested for medical or pharmaceutical device applications. Users must confirm suitability, and the information does not replace specific validation for regulated uses.
