Sealants, Resins & Adhesives
FAQs
Sealants, resins and adhesives are used to secure, protect and weatherproof installations in telecoms, fibre, and electrical projects. Typical on-site uses include:
- Sealing cable entry points to prevent water or dust ingress
- Mounting surface boxes, trunking or cable anchors
- Jointing underground ducts using resins
- Firestopping around cable penetrations
- Gap filling in wall or floor access points
These products are essential for durability, safety compliance and neat installation finishes.
Choosing the right product depends on the application:
- Decorators caulk for indoor sealing around trunking & conduit
- Silicone sealants for weatherproofing outdoor cable entries
- PU foam for filling large gaps & insulation around ducts
- Resins & encapsulation compounds for waterproof joint closures in underground chambers
- Fire resistant compounds for firestopping around cable penetrations
- Adhesives (grab/contact) for fixing cable clips, mounting boxes or panels
- Putty/Sealant clay for quick sealing of small entry holes
- Thinners & cleaners for cleaning tools and removing excess sealant
Fire resistant sealants are required when cables pass through fire rated walls, floors or risers in buildings. These products:
- Maintain the fire integrity of walls and floors
- Prevent the spread of fire, smoke and gas
- Are commonly required in data centers, schools, hospitals and commercial installs
Look for intumescent sealants and firestop putty compliant with EN 1366 or BS 476 standards.
Installation typically requires:
- Caulking guns for silicone and decorator’s caulk cartridges
- Foam applicator guns for expanding foams
- Mixing sticks & nozzles for two part resins
- Spatulas & applicators for putty and smoothing finishes
- Cleaning wipes or thinners for equipment and surface cleaning
Using the right applicator ensures clean, professional seals and reduces wastage.
