Natural Polymers for Adhesives and Sealants

Cardolite® NC-514 is a diglycidyl ether epoxy resin. Cardolite® NC-514 provides excellent flexibility, outstanding water resistance, and increased bond strength on difficult substrates like wet or oily surface. Cardolite® NC-514 is considered bio-based alternative for Bis-A based epoxy resin. It is recommended for 1K/2K epoxy adhesives and sealants as a toughener. It is used in industrial, transportations, and electrical/electronic adhesives to provide toughness, flexibility and water resistance.

Cardolite® LITE 513DF by Cardolite is a low viscosity epoxy reactive diluent and modifier based on cashew nutshell liquid (CNSL) technology. It has long hydrophobic aliphatic side chain which provides excellent water- and thermal shock resistance.

• It is an excellent alternative to difunctional diluents for increased strengths and hydrophobicity.
• Used for transportations, industrials, constructions and electronics applications.
• Partial substitution of liquid epoxy (Bis-A) with Cardolite® LITE 513DF offers well balanced mechanical strength and flexibility while increasing bio-content.
• The recommended usage levels can be 30-100% in reactive systems such as 1K and 2K epoxy adhesives and sealants.

Cardolite® NX-9014 by Cardolite is a low viscosity polyol with improved color stability. It offers excellent water resistance, improved QUV resistance, high tensile strength and excellent bond strength on various substrates including steel, aluminum, composites, and plastics. Cardolite® NX-9014 is suitable for use in polyurethane based structural adhesives and sealant applications like windmill OEM, polyurethane pottings and high strength foams and composites. It can be formulated with aliphatic isocyanates for color stable adhesives and sealants, and coatings.

Cardolite® NX-9011 by Cardolite is a low viscosity non-CNSL branched polyol. It offers high tensile strength and flexibility. Exhibits excellent bond strength on various substrates including steel, aluminum, composites and plastics. Cardolite® NX-9011 is suitable for use in polyurethane based structural adhesives and sealant applications like windmill OEM, polyurethane pottings and high strength foams and composites.

Cardolite® NC-514S is diglycidyl ether epoxy resin with low viscosity. Cardolite® NC-514S provides excellent flexibility, outstanding water resistance, and increased bond strength on difficult substrates like wet or oily surface. Cardolite® NC-514S is considered bio-based alternative for Bis-A based epoxy resin. It is recommended for 1K/2K epoxy adhesives and sealants as a toughener It is used in industrial, transportations, and electrical/electronics adhesives to provide toughness, flexibility and water resistance.

Cardolite® NX-9201 is a low viscosity di-functional CNSL polyester diol by Cardolite. It offers excellent moisture resistance and hydrolytic stability in aqueous solutions. Its reactivity with isocyanates is greater than other types of diols. Compatibility with polyether diols and Poly BD are outstanding, thus, when Cardolite® NX-9201 is blended with other diols, it shows significant improvement of hydrolytic stability. It can be used in 1K/2K polyurethane adhesives and sealants, coatings, elastomers and flexible foams.

Natrosol™ 250 HXR by Ashland is a fine powder, hygroscopic, water soluble hydroxyethylcellulose. It acts as a non-ionic viscosity- and rheology modifier, protective colloid, stabilizer, water retention- and suspending agent. It is suitable for water-based adhesives.

• It is treated to delay hydration of the particles.
• It shows compatibility with other materials such as emulsion polymers, natural and synthetic gums, emulsifiers and defoamers.
• It offers very good flow with fine particle size.
• Natrosol™ 250 HXR is used in tile adhesives.
