TDMA-G55

Product Name: Eco-friendly Liquid Chain Extender / Liquid Crosslinker

Typical Properties：

Solubility：Easily soluble in various polyether polyols / chlorinated plasticizers.

Environmental protection: 

It does not contain restricted heavy metals, o-benzene plasticizers and other environmentally restricted substances, does not contain MOCA components, and has no DMTDA (E300) odor. The plastic runway resin synthesized with this product complies with relevant environmental regulations.

Applications：

It is widely used in polyurethane resin of plastic runway and sport track.

Features & Advantage:

TDMA-02/TDMA-G55 is a new environmentally friendly liquid chain extender, which is applicable to the most stringent requirements of Shanghai Plastic Sport Track Standard. It not only enhances the hardness and strength (tensile strength) of the sport track, but also balances the toughness (tear strength and elongation), deformation and impact resistance, and technically shortens the post solidification time. It has the following characteristics::

• The product is non-toxic and odorless. It does not contain MOCA ingredients and has no special odor of DMTDA (E300), which complies with stringent environmental regulations.

• It is liquid at normal temperature and easy to use. It can be well miscible with other raw materials without heating, which is convenient to use. Although the viscosity increases at low temperature, it is still liquid and generally will not crystallize.

• Moderate activity, convenient for construction. It has lower activity than DMTDA (E300) but higher activity than MOCA. Collocate with CUCAT-V series or bismuth zinc catalyst, the construction time can be as long as more than 40 minutes, and it can be cured in 12 hours, which is convenient for construction.

• Excellent physical properties, improved hardness, tensile strength and other mechanical indicators. After properly adjusting the formula, the physical properties are equivalent to those of MOCA and DMTDA.

• The price is low and the cost advantage is obvious. It is one of the most cost-effective products in the market at present, and its price is close to MOCA, less than half of DMTDA (E300). In most of the formulas of MOCA currently used, use TDMA-02 to replace MOCA with dosage of 70% of MOCA amount, the performance of the product still meets the standard after curing.

• The material with TDMA-G55 has good operability, and the material with TDMA-02 has better physical properties.

• It can be used as a quick curing agent for thick coating. Combined with conventional silicon PU, it can be thick coated for more than 8mm at a time, forming without bubbles, and curing faster at low temperature.

User's Guide:

• For two-component runway materials, the operation process is the same as MOCA, and it is more convenient to use in liquid state. If the adhesive formula is synthesized by part of M=1000 or MN3050 polyether polyol and isocyanate (such as MDI50), the performance will be better.

• For silicon PU formula, the addition amount is 1-2% of the amount of silicon PU, it is recommended to be added on site during construction and carry out subsequent construction after thorough mixing. The specific dosage depends on the formula, which is recommended to be determined after a small test.

Handling & Storage:

Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain.

Package: 25kg/200kg in HDPE drum

Shelf Life: The unopened shelf life is 24 months from the date of manufacture. After the shelf life, it can still be used normally after passing the test. Please pay attention to seal before store.
