ChemLink M-1 Clean Room Adhesive Sealant (F1224): The Ultimate Solution for Contamination Sensitive Environments

ChemLink’s M-1 Clean Room Adhesive Sealant (F1224) is an advanced elastomeric sealant engineered for environments where air quality and material purity are critical. Leveraging cutting-edge polymer chemistry and strict regulatory compliance, M-1 CR stands out as the preferred choice for cleanrooms, healthcare facilities, and other contamination-sensitive applications.

Core Characteristics of M-1 Clean Room Adhesive Sealant

Non-Toxic, Safe Formulation

• Solvent/Isocyanate-Free: 

M-1 CR contains no solvents or isocyanates, eliminating health risks from volatile organic  compounds (VOCs <15 g/L) and toxic chemicals. This makes it ideal for use in hospitals, schools, and other occupied spaces.

• Zero Outgassing:

Unlike traditional urethane sealants, M-1 CR produces no molecular air contamination—even when  applied to damp surfaces. This property is crucial for semiconductor cleanrooms and biomedical facilities where air purity is paramount. 

Exceptional Performance Under Extreme Conditions

• Temperature Resilience: 
  Cures effectively at 32°F (0°C) and withstands continuous service temperatures up to 200°F (93°C). 
• UV and Weather Resistance: 
  Maintains color stability and elasticity without cracking or discoloration, even after prolonged UV exposure.

Structural Flexibility and Application Versatility

• 35% Joint Movement Capacity: 
  Accommodates thermal expansion and contraction in substrates like PVC, TPO, and concrete without losing adhesion.
• Non-Slumping Application: 
  The thixotropic formula allows for vertical or overhead application, preventing sagging or dripping.

Regulatory & Industry Compliance

• Cleanroom Certification: 
  Approved for use in semiconductor and aerospace cleanrooms, meeting ASTM C920 (Type S, Class 25) and Federal Specification TT-S-00230-C.
• Environmental Standards: 
  
  • CARB, SCAQMD, and LEED-compliant for low emissions.
  • USDA-approved for non-food contact areas in food processing plants.

Applications Beyond Cleanrooms

While M-1 CR is optimized for contamination-controlled environments, its versatility extends to:

• Healthcare: 
  Sealing surgical suites, laboratories, and other spaces where air quality is critical.
• Education: 
  Ideal for "Healthy Schools" initiatives due to its non-toxic, low-emission profile.
• Infrastructure: 
  Waterproofing bridges and soundwalls, thanks to its resistance to ponding water and chemicals.

Installation Advantages

• Rapid Cure Time: 
  Skins over in just 30 minutes and achieves full cure in 24 hours, accelerating project timelines.
• No Priming Required: 
  Bonds directly to most substrates, including metals and membranes, reducing surface preparation. 
• Ease of Use: 
  Supplied in 10.1 oz cartridges (case of 16), compatible with standard caulking gun —no specialized equipment needed.
