Selecting Tackifiers for Adhesives and Sealants
Tackifiers operate opposite to plasticizers which lower the Tg of the adhesive formulation. The tackifying agent must be compatible with the base polymer. With hot-melt adhesives, consideration must also be given to the heat stability of the tackifier in the melt.
5 Most Important Additives for Waterborne Adhesives
Ideally, plasticizers should be: Highly compatible with polymers, Stable in both high and low temperature environments, Sufficiently lubricate over a wide temperature range, Insensitive to solar ultraviolet radiation, Leaching and migration resistant, Inexpensive, Fulfilling health and safety regulations.
Natural-based plasticizers and biopolymer films: A review
Besides, considering the plasticization efficiency and storage stability for chitosan films, GLY and PEG showed to be more suitable than EG and PG. Furthermore, a plasticizer concentration of 20% (w/w) with GLY or PEG was sufficient to obtain flexible chitosan film, exhibiting good stability for 5 months of storage.
A highly stable bio-based plasticizer constructed from renewable acids
The current research efforts in the plasticizer industry should focus on finding renewable biomass chemical feedstocks to synthesize non-toxic and effective bio-based plasticizers in order to adapt to the concept of green environmental protection given the scarcity of petroleum resources and the growing emph
- What is a tackifier resin?
- Pinerez® tackifier resins are recommended to enhance the adhesive performance in hot-melt and solvent-based adhesive applications. They are stabilized, light-colored resins with excellent viscosity stability, and have excellent compatibility with a range of polymers that are widely used in packaging and pressure-sensitive adhesives.
- Does tackifier increase Tg?
- Therefore, the tackifier addition raises the Tg of the final adhesive. Tackifiers operate opposite to plasticizers which lower the Tg of the adhesive formulation. The tackifying agent must be compatible with the base polymer. With hot-melt adhesives, consideration must also be given to the heat stability of the tackifier in the melt.
- How do I choose a tackifier for a hot-melt adhesive?
- With hot-melt adhesives, consideration must also be given to the heat stability of the tackifier in the melt. Tackifiers with unsaturation could potentially gel while the adhesive is in the melt phase. They should also have a relatively low surface tension so as to readily wet the substrate.
- What is tackifier & plasticizer?
- Due to the molecular property of the resin the tackifier quicky travels to the substrate on the compound providing the much needed building tack. Plasticizer: These resins contribute as plasticizers during the compound of the rubber compound.
- What types of plasticizers are used in adhesives & sealants?
- Oils (like paraffinic, naphthenic, and aromatic) are used mainly as plasticizers in non-polar adhesives. These are generally used in the hot-melt adhesives and sealants. Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants.
- Why are Tackifiers important?
- Tackifiers are important constituents in adhesives formulations in order to maintain the correct balance between adhesion and cohesion. They must be considered with regard to the end-used properties, adhesive processing as well as compatibility with base polymer to achieve desired performance requirements.
