How to Choose a Two Components IG Sealant Supplier
Assessing Product Quality
Selecting the right two components ig sealant starts with a close look at product quality. Decision-makers should use both visual and hands-on checks. Here are some practical steps:
1.Observe the glossiness of the sealant. High-quality sealants keep a consistent, glossy finish.
2.Smell the sealant. A lighter acidic scent often means better quality.
3.Check the texture. The surface should be fine, even, and smooth.
4.Inspect for air bubbles during application. Good sealants do not produce bubbles.
5.Test softness and hardness after curing. The right balance supports long-term performance.
A butterfly test can help check if the base adhesive and curing agent are mixed well. This test is important for ensuring the sealant performs as expected.
| Criteria | Description |
|---|---|
| Longevity | The expected lifespan of the sealant under normal conditions. |
| Tack-free time | The time it takes for the sealant to become non-tacky after application. |
| Shrinkage | The amount the sealant may shrink as it cures, affecting its performance. |
| Moisture vapor transmission | The ability of the sealant to allow moisture vapor to pass through, which can impact insulation. |
| Shear adhesion | The strength of the bond between the sealant and the surfaces it adheres to. |
| Air entrapment | The presence of air bubbles within the sealant, which can compromise its integrity. |
Importance of Certifications
Certifications show that manufacturers meet industry standards for safety and quality. Look for programs like ALI/AAMA Sealed Insulating Glass Certification and AAMA Product Certification. These programs confirm that glass glazing sealant products pass strict tests. Compliance with ASTM E-2190 is also important. This standard checks for moisture resistance and long-term durability. Meeting standards such as CAN/CGSB-12.8 or ASTM E2190 is necessary for ENERGY STAR® and NFRC ratings. Proper glass washing and high-quality sealants help ensure certification success.
| Certification Program | Description |
|---|---|
| ALI/AAMA Sealed Insulating Glass Certification Program | Offers IG certification through its Gold Label administrator, Associated Labs, Inc. (ALI). |
| AAMA Product Certification Program | Provides IG certification with potential cost and scheduling savings for companies already in the AAMA air-water-structural certification program. |
