What is tackifier made of?

What is tackifier made of?

Hydrocarbon resins are the most popular tackifiers. They are produced mainly from petroleum-based by-products of naphtha crackers. The three major types are C5 aliphatic, C9 aromatic, and DCPD cyclo-aliphatic resins. They are sometimes hydrogenated to reduce discoloration and to improve their heat and UV stability.

What is hydrocarbon resin used for?

Hydrocarbon resins are highly versatile products capable of performing crucial functions in many applications – such as in the production of adhesives, rubber, coatings and inks. Because they are good tackifiers, the resins are especially critical to the manufacture of adhesives.

What is a C5 resin?

C5, Aliphatic Resins are so named because they are generally polymers of monomers with five carbons. Basic C5 aliphatic resins have Gardner colors between 1.5 and 6 (from light yellow to light brown) and are mostly used to tackify aliphatic polymers, especially natural rubber, EVA, SIS and APO.

Is tackifier organic?

M-Binder tackifier is a botanical glue used in hydroseeding, to stabilize soils and for dust control. Derived from the seed of the plantego plant (Plantago insularis), M-Binder is 100% organic, non-toxic and biodegradable. Use anywhere you need to “tack” down seed, straw or mulch, or to control dust and erosion.

How does a tackifier work?

Tackifiers work by reducing the modulus and increasing the glass transition temperature (Tg) of the resulting adhesive formulations. Both these factors are critically important to achieve the necessary tack and peel strength.

What is C5 in petroleum?

The C5 (C5) fraction is a co-product of naphtha cracking and is used as a raw material for synthetic rubber and petroleum resins.

What is the difference between C5 and C9?

These resins are available in a wide range of softening points. Compared to C5 resins, they have a much higher melt viscosity, are of darker color (dark yellow to brown)2 and have higher softening point ranging from about 100 to 150°C. C9 resins are very versatile resins that are compatible with many polymers.

What makes a good tackifier?

Tackifiers tend to have low molecular weight, and glass transition and softening temperature above room temperature, providing them with suitable viscoelastic properties.

Which chemical is used for resin?

Composition. Most plant resins are composed of terpenes. Specific components are alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and delta-cadinene.

What is C1 C2 C3 C4 C5 gas?

Hydrocarbon (Organic) Gases C1 = methane; C2 = ethane; C3 = propane; C4 = butane.

What is C9 chemical?

The C9 (C9) fraction is a co-product of naphtha cracking and is used as a raw material of petroleum resins.

What is C9 resin?

Hydrocarbon Resin is a C9 aromatic hydrocarbon used in industrial applications. It has a tackifying effect and is suitable for use in paint, printing ink, adhesives, rubber and other areas where tackiness is required.

What is Hydroseed tackifier?

Hyrdoseeding is applying a slurry of water, wood fiber mulch, seed and fertilizer to prevent soil erosion and provide an environment conducive to plant growth. Hydromulching is applying a slurry of water, wood fiber mulch, and often a tackifier, to prevent soil erosion. These terms are often used interchangeably.

What is a tackifier in formulating?

Tackifier. Tackifiers are chemical compounds used in formulating adhesives to increase the tack, the stickiness of the surface of the adhesive. They are usually low- molecular weight compounds with high glass transition temperature. At low strain rate, they provide higher stress compliance, and become stiffer at higher strain rates.

What should be considered when choosing a tackifying agent?

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. Tackifiers with unsaturation could potentially gel while the adhesive is in the melt phase.

What Tackifiers are used in acrylic adhesives?

Some acrylic adhesives also include an additional tackifier. Silicone rubber –based pressure-sensitive adhesives require special tackifiers based on “MQ” silicate resins, composed of a monofunctional trimethyl silane (“M”) reacted with quadrafunctional silicon tetrachloride (“Q”). Tackifiers are also used in tyres.

What is the difference between Tackifiers and plasticizers?

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.
