Applications
- Sealing of moving joints between building and facade elements.
- Sealing of window and door frames, insulation boards, construction panels, partitions,penetrations, holes, cavities and more.
- Ideal for both small and large joints.
- Flexible and airtight sealing of movement joints, connections, seams, gaps and holes, such as between/along interior and exterior walls, cavity walls, partitions, ceiling, roof and floor elements.
- Sealing and filling installation spaces between, along and around building and facade elements, such as prefab wooden and concrete components, aluminum, steel, wooden and plastic facades, window and door frames.

Properties
- Extremely low expansion pressure and post-expansion.
- Flexible quality, can absorb movements excellently.
- Meets emission class M1 GEV-Emicode EC1 PLUS.
- Durable weather, water, moisture and aging resistance.
- Cured foam can be painted over.
- 1K isocyanate free, specially developed as flexible insulation and assembly foam where there is no training requirement.
- Excellent adhesion to stone, stucco, plaster and masonry, concrete, gypsum, metals, wood and many plastics, such as styropor (polystyrene), PU rigid foam, polyester, rigid PVC and composite.
- High thermal and acoustic insulation values, economical, reduces heat loss and sound transmission.

Application conditions
- Application temperature (ambient and substrate) between min. +5°C and max. +40°C.
- On tolerable, load-bearing, clean and grease-free substrates.
- Remove loose substrate particles with a suitable brush.
- Thoroughly degrease substrates using Seal-it® 510 CLEANER.
- Before use, shake the can about 20 times vigorously/well.
- If necessary, pre-moisten the substrate slightly, using a plant sprayer.
- Cut off completely cured excess Seal-it® 430 HYBRI-FOAM with a knife and/or trowel.
- Grease thread of gun adapter with Vaseline, PTFE and/or silicone spray before use to prevent the canister from sticking to the Pur gun.
- After fixing the Pur-gun on the canister, the spraying speed and volume output can be adjusted by means of the setting screw at the rear of the gun, in order to achieve efficient / economical use.
- When not in use, close adjusting screw at rear of Pur gun until Pur gun can no longer be activated.
- Always leave the canister on the Pur gun until it is completely emptied.
- Remove an empty canister by simultaneously squeezing the gun trigger while unscrewing it to release any remaining propellant.
- Then replace the Pur gun on a full canister, and/or clean the Pur gun thoroughly, using Seal-it® 450 PUR CLEANER.
- If a PUR gun does not work and/or does not function properly, place Seal-it® 450 PUR CLEANER on the PUR gun, spray through several times and allow to work in thoroughly for about 15 minutes. Spray through again and then remove the can of Seal-it® 450 PUR CLEANER.
