상품 소개

Polyurethane foam sealant is dispensed from a pressurized aerosol can as a moisture-reactive cellular material. It expands within irregular concealed voids, adheres to many common construction substrates and cures into a lightweight insulating fill that can be trimmed after hardening. In cleanroom work it is normally kept behind the exposed hygienic finish, with the accessible joint subsequently closed using a smooth compatible sealant or trim profile.

주요 기능

Controlled expansion reaches irregular frame and panel cavities that are difficult to pack manually.

The cured closed- and open-cell structure reduces uncontrolled air movement through concealed gaps.

Adhesion to compatible concrete, masonry, timber, metal and rigid insulation stabilizes the filled cavity.

Hardened excess can be cut back to receive a cleanable cover trim or surface seal.

고객 제품 관심사

Irregular installation cavities need a continuous insulating fill without allowing expanding foam to become the exposed cleanroom surface.

Rigid packing leaves small inaccessible voids behind frames.Fresh foam expands into uneven spaces and bonds to prepared cavity surfaces.

Excessive expansion can bow lightweight panels or distort frames.A low- or controlled-expansion grade is applied in measured lifts with room left for curing growth.

Exposed cellular foam is difficult to clean and can degrade under light.The cured fill is trimmed below the face and protected by a smooth compatible sealant or cover profile.

Dry or dusty substrates produce weak and uneven cure.Surfaces are cleaned and lightly conditioned with moisture where the selected product instructions permit.
