TRANSTAR® 4502 is a high‑performance windshield adhesive supplied in an 11 oz paste cartridge. It is formulated for permanent bonding of automotive glass to primer‑treated substrates, providing a reliable seal for both new installations and repairs.
The adhesive offers a 24‑ to 36‑hour cure window, allowing ample work time while achieving full strength within the specified period. With a VOC content of 0.55 lb/gal (66 g/L) and a one‑year shelf life, it meets emissions standards and remains usable for extended storage. Designed for use over primer, it ensures consistent coverage and strong adhesion to the glass‑to‑frame interface.
Because the formulation includes acute toxicity, aspiration hazards, and is classified as a carcinogen, appropriate personal protective equipment is required: eye protection, chemical‑resistant gloves, protective clothing, and a respirator. Use in a well‑ventilated area and follow the SDS first‑aid guidelines for inhalation, skin, and ingestion exposure.
