Substrate / Material Compatibility



	Your choices are...
	Ceramic / Glass		Ceramics consist of oxides, carbides, nitrides, carbons, and other non-metals with high melting points. Ceramics are suitable for applications requiring wear resistance, refractoriness, low electrical resistivity, or other specialized characteristics.
	Concrete / Masonry		Concrete and cements consist of a mixture of a binder or clinker and a coarser aggregate used to patch, line floors or walls, bond together brick, and join components for use in high-temperature applications. Clinker is a fused mineral or mineral mixture, such as alumina or bauxite and lime, which is crushed into a fine powder to manufacture cements. Aggregates are coarser, granular materials that are added to mortar, grout, or cement at time of mixing to impart special properties (refractoriness, erosion resistance, oxidation resistance). Synthetic aggregates are fused mineral or mineral mixtures crushed to a coarse granular size range rather than a fine powdered clinker. Portland cement is the most common bond used in structural concretes and mortars. Polymer cements have a resin bond and are used in corrosion protection, mortars for corrosion resistance floor tiles and other specialized industrial applications. Masonry consists of tile, bricks, stone, or other ceramic components bond together with mortar or adhesive.

Open-cell materials are considered porous and are often used for filtering and reservoir applications. The adhesive should have chemistry and wetting characteristics compatible with the foam polymer. The adhesive consistency and viscosity is adjusted for foam or porous materials.
	Polyurethane Foam		Polyurethane or PUR resins provide excellent flexibility, impact resistance, and durability. Polyurethanes are formed through the reaction of an isocyanate component with polyols or other active hydroxyl group compounds. Polyurethanes require a catalyst, heat, or air evaporation to initiate and complete curing.
	Porous Surfaces		Porous surfaces are capable of bonding to porous materials or rough surfaces such as open-celled foams, concrete, and sintered materials. Typically, adhesives or sealants with a high viscosity or gel-like consistency function with porous or rough surfaces.

	Reflective		Reflective products are highly visible and provide warnings about unsafe conditions. Reflective tapes are used in rotating or moving equipment to trigger proximity sensors, or enable a tachometer to make readings.
	Removeable		Removable tapes can be applied and then removed without damaging the substrate, but not necessarily reused or repositioned.
	Repositionable		After application onto a substrate, the tape can be removed and/or repositioned indefinitely - or at least during assembly - without damaging the substrate or tape product.
	Sealable / Controlled COF		Sealable or controlled COF films or liners are designed with a controlled coefficient of friction to allow control of sealing, slip, or bonding between layers.
	Shrink Film / Wrap		Shrink film or shrink warp is a plastic film (usually polyethylene, polypropylene, or polyvinyl chloride) that is wrapped loosely about another product or container and then made to shrink tightly about the container or product by the brief application of heat, usually in a hot air tunnel.
