PIB primary sealant

FS 210 PIB primary sealant is a solvent-free sealant based on polyisobutylene for the internal insulation (first-barrier) of double glazed units. The formulation has been specially developed to achieve minimum water vapour and gas permeation, ageing UV resistance, excellent adhesion properties on glass and aluminum.

Features of PIB primary sealant:

• Excellent adhesion to glass, aluminium, galvanised steel, stainless steel and tinplate spacer bar and metal and plastic corner keys
• Minimum water vapour and gas permeation
• Easy application by standard dispensing equipment
• UV resistance
• No cleaning or purging of dispensing equipment required
• Can also be used as a handling aid in rigid spacer bar unit production.

Specifications of PIB primary sealant:

Packaging of Polyisobutylene Sealant:

Carton (1,5 kg / 2,5 kg /3,0 kg / 7,0kg) or customized

Storage of Polyisobutylene sealant:

FS 210 sealant has a shelf life of 24 months when stored in its original containers. For optimal performance, it is recommended to store it in dry and cool rooms with temperatures maintained between +10 C and +30 C.

FAQ:

Achieving stable and high-quality butyl sealant to spacer is a perennial topic in the production process. Even the slightest deviation can lead to defects in the final product.

Key Points:
* **Temperature Control:** PIB Butyl rubber is extremely sensitive to temperature. Excessive heat causes the adhesive to become too thin and flowy; insufficient heat results in poor flowability, making extrusion difficult and prone to breakage.
* **Coating Uniformity:** Ensuring consistent width and thickness of the adhesive strips without burrs is crucial. This requires precise equipment adjustments and a stable production line speed.
* **Substrate Cleanliness:** Dust and oil on the aluminum spacer surface can severely affect the adhesion of the butyl rubber, leading to seal failure.
