Additives Curing Agents Pressure Sensitive Adhesives

 

Advantages of Additives for Pressure Sensitive Adhesives

Enhanced Adhesion: Additives can improve adhesion to specific substrates, including low surface energy materials.

 

Increased Cohesion: Crosslinking agents and functional monomers can enhance the internal strength of the adhesive, preventing it from breaking down under stress.

 

Improved Temperature Resistance: Additives can help PSAs maintain their performance across a wider temperature range, including extreme heat or cold.

 

Customized Properties: Additives allow for tailoring the PSA's properties, such as tack, peel strength, and shear strength, to meet specific application needs.

 

Improved Processing: Plasticizers and other additives can improve the flow and handling characteristics of the adhesive during manufacturing.

 

Enhanced Durability: Additives can increase the resistance of the adhesive to environmental factors like moisture and chemicals.

 

Types of Additives for Pressure Sensitive Adhesives

 

Tackifiers

Generally, tackifiers or blends of tackifiers are added to the base polymer in pressure sensitive formulations. Rosin ester tackifier resins were used in early pressure sensitive adhesive formulations. They have been largely replaced by better aging terpene resins, which provide excellent performance characteristics.

01

Plasticizers

Plasticizers are mainly used in rubber based adhesives to reduce cost. The effect of plasticizer addition on tack is quite variable. However, they generally reduce peel and cohesive strength. This can be useful in certain applications such as reducing peel adhesion to unwind pressure sensitive tapes.

02

Antioxidants

Many of the base polymers used in pressure sensitive adhesive formulations contain unsaturated double bonds along the chain and, therefore, are subject to oxidative attack. This is usually aggravated by exposure to elevated temperature or ultraviolet light. These degradative factors can occur during processing or end-use. Consequently, antioxidants are used to stabilize the adhesive against oxidation and heat and light degradation.

03

Pigments

Pigments or fillers are added to pressure sensitive adhesive formulations for coloring and to improve performance - notably cohesive strength and tack retention. Pigments have also been used to reduce the material cost of the adhesive.

04

Reinforcing Fillers or Crosslinking

In many applications, such as heavy-duty strapping tape, creep resistance is very important. The creep resistance of pressure sensitive adhesive can be improved by using reinforcing fillers or crosslinking. Crosslinking can be either chemical or by exposure to radiant energy such as electron beams.

Application of Additives for Pressure Sensitive Adhesives

 
 
Healthcare Industry

They are used in wound care, surgical procedures, and wearables. For these uses, the adhesive needs to be breathable and comfortable while also maintaining good durability.

 
Packaging Industry

In the packaging industry, pressure sensitive adhesives help seal boxes and labels quickly and securely. Since these adhesives do not require heating or drying, the packaging process can be accelerated and more efficient.

 
Automotive Industry

Automotive applications also rely on the functionality and design of pressure sensitive adhesives. Pressure sensitive adhesives are used to connect various parts inside cars without drilling or welding, which can damage materials or create weak points.

 
Electronics Industry

In electronics, pressure sensitive adhesives are used to bond lightweight parts. As devices become smaller and lighter, adhesives must be thin but strong.

A: Yes,we are the additives manufacturer in China. ISO 9001, ISO 14001 and ISO 45001 certificates for ACME and Surfadol factory; REACH certificates.

Q: How long is your delivery time?

A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.

Q: Do you provide samples? is it free or extra?

A: Yes, we could offer the sample for free charge and pay the cost of freight if you sincerely test.

Q: What's the payment terms?

A: 100% T/T in advance or 30 days against the BL date.

Q: Do you accept custom orders?

A: Yes, customized service is available. Our company has an advanced research and analysis testing laboratory and a technical team with over 20 years of professional experience.

Q: What factors should be considered when selecting PSA additives?

A: Application requirements:
The specific needs of the application, such as temperature, humidity, and type of substrate, will dictate which additives are most appropriate.
Substrate material:
Different substrates have varying surface energies, which can affect the adhesive's ability to wet out and bond.
Regulatory requirements:
Some additives may be restricted or require specific labeling, depending on the application (e.g., food contact).
Cost:
The cost of additives can vary significantly, and the optimal balance between performance and cost needs to be considered.
Processing conditions:
Some additives can affect the viscosity of the adhesive, which may impact processing methods.

Q: How do additives affect PSA properties?

A: Tack:
Tackifiers increase tack, while plasticizers can either increase or decrease tack depending on the type and amount.
Peel Adhesion:
Plasticizers can reduce peel adhesion, while crosslinkers can increase it.
Cohesive Strength:
Crosslinkers and fillers can improve cohesive strength, while some plasticizers can decrease it.
Temperature Resistance:
Crosslinkers and some fillers can enhance resistance to high and low temperatures.
Shelf Life:
Antioxidants and UV stabilizers can improve shelf life and resistance to environmental factors.

Q: How long does a pressure sensitive adhesive take to cure?

A: The curing time for PSAs can vary depending on several factors, including the specific formulation of the adhesive, the materials involved, the environment, and the application pressure. Most PSAs provide an instant bond and achieve their full bond in several to 72 hours.
