Phthalate, Fast Fuser With Excellent Permanence, Performance Characteristics, And Paintability

Santicizer® 278 is extremely permanent. It resists exudation and extraction and has very low volatility. Additionally, Santicizer® 278 has shown sound dampening benefits, and has benefits in wet applications of paint.

Santicizer® Benzyl Esters as seal swell additives

In crankcase oils, transmission oils and hydraulic fluids the lubricant is in contact with the seal. Those seals can be made of different elastomers. The generally used elastomers are:

• nitrile butadiene rubber (NBR)
• acrylic
• silicone
• fluorinated

While aging, these elastomers tend to become harder (even brittle), tend to shrink and they tend to lose their elastomeric properties (as elongation). When this aging goes along with higher temperatures, as in automotive crankcase oils, this process is even accelerated.

The loss of those elastomeric properties in an engine can be the cause of leaks and thus loss of oil. But in order not to lose the properties of the elastomers and thus prevent leakage some polar additives have to be introduced. Those have to be as compatible as possible with the different elastomers. Alkyl benzyl esters, Santicizer® 261A, Santicizer® 278, Santicizer® Platinum P-1400 & P-1700, are good compatibilizers at a low dosage of 1 to 4 wt% for different type of elastomers. In the volume change aging test according the norm CEC-L-39-T-96 the addition of a seal swell additive as a benzyl ester is necessary to avoid shrinkage of the seal when put in a pure poly alpha olefin.

Polyurethane systems offer a wide variety of desirable performance features in coatings, adhesives, caulks, sealants and castable applications. Polyurethanes are used for their flexibility, excellent durability, tear resistance, and resilience. Valtris Santicizer phthalate and non-phthalate plasticizers are well suited for polyurethane applications, both 1K and 2K formulations.

Benefits of using Valtris plasticizers:

• Enhance processability by modifying rheological properties.
• Reduce elastic modulus and shore A hardness.
• Improve flexibility and maintain mechanical properties.
• Polar molecules, therefore, highly compatible with excellent permanence in urethane technology.
• Low Hydroxyl number and low moisture content.
• Low neat color.
• Excellent abrasion resistance

SPUR: Silylated Polyurethanes. SPURs have a silane curing mechanism and a polyurethane backbone, but they do not contain the unreacted isocynates like standard polyurethane technology. This makes them more esthetic to the environment and they have become increasingly appealing to adhesives, sealants and coatings. SPUR formulations offer fast room-temperature cure and good durability when compared to a standard polyurethane system. Generally, a plasticizer is used in a SPUR formulation because of the need for specific properties the plasticizer can provide that the formulator is not able to reach on its own. Valtris plasticizers are compatible with SPUR technology and can offer properties not seen with standard SPUR formulations.

Benefits of using Valtris plasticizers:

• Enhance processability by modifying rheological properties.
• Reduce elastic modulus and shore A hardness.
• Improve flexibility and maintain mechanical properties.
• Offer better low temperature flexibility.
• Low Hydroxyl number and low moisture content.
• Low neat color.

Modified silane polymers were developed 30 years ago, and we have seen a large increase in both the European and North American markets due to its great advantage of being an elastic adhesive compared to polyurethane and PVC adhesives. Modified silanes are one component adhesives which react and cure under the action of moisture, and once cured acquire elastic properties and strength of an elastomeric material. Valtris Santicizer phthalate and nonphthalate plasticizers are well suited for MS Polymer formulations.

Benefits of using Valtris plasticizers:

• Enhance processability by modifying rheological properties.
• Reduce Shore A Hardness.
• Improve flexibility and maintenance of mechanical properties.
• Equal tack time and cure through
• Better Water Sensitivity

Plastisol inks are the most commonly used products in garment printing. They are easy to print and do not dry on the screen. Plastisol inks can be used on both light and dark garments, and can adhere to most textiles. Plastisol Inks will not dry, or cure, at normal temperatures, they must be cured with heat. Plastisol inks actually bond to the fiber in the garmet instead of coloring the fiber like a dye. They are touted for having great color consistency. Plasticizers are added to the plastisol ink to give it good prinitability, water wash, and to help control bleed through, as well as many other properties.

Benefits of using Valtris plasticizers:

• Improve flexibility and mechanical properties (tensile and elongation)
• Excellent permanence attributes.
• Excellent water wash capabilities.
• Good printability, high DYNE pen surface energy
• Low bleed through
• Increased gelation and cure time
