Description

Specifications

Advanced Polyurethane Bonding Technology

JR‑996 is a one‑component moisture‑curing PU adhesive sealant for automotive direct glazing. Its primer‑less, solvent‑free, non‑sag thixotropic formula enables clean vertical application without runs, and yields a bubble‑free smooth finish that enhances appearance and reduces rework.

The product's high initial grab secures windshields immediately after assembly even before full cure, cutting clamping time; upon moisture exposure, it cures into a durable weather‑resistant elastomer that accommodates differential expansion and ensures long‑term sealing under severe conditions..

Why Choose JR-991?

High Initial Grab Strength

Provides strong early holding force to keep automotive glass securely positioned before complete curing.

Non-Sag Formula

Thixotropic formulation enables easy application on vertical surfaces without dripping or running.

Primer-Free Solution

Solvent-free and primer-less formulation reduces processing steps while protecting substrates.

Smooth Surface Finish

Bubble-free curing creates a smooth and fine appearance after application.

Weather Resistant Bond

Forms a durable elastomeric bond that withstands environmental changes.

Flexible Expansion Adaptation

Accommodates different expansion rates between glass and metal components.
