Example 1.
Parts polyol100
1. Extend a straight line from the DURANATETM NCO value on Axis A, through the polyol’s OHV value on Axis B, to intersect Axis C.
2. Read the value on Axis C at the intersection, as the required DURANATETM quantity for an NCO/OH ratio of 1.
3. Multiply the above reading by the desired NCO/OH ratio, if the ratio is different from 1.
Note: (1) For a DURANATE™ grade having NCO<14%,
use twice the actual NCO value in Step 1 and then multiply the value on Axis C in Step 2 by two, to obtain the required quantity for NCO/OH = 1.
(2) For a polyol having an OHV value outside the Axis B range, multiply the actual OHV value by an appropriate factor (fraction or integer) to obtain an adjusted value within that range, use the adjusted value as the OHV value in Step 1, and multiply the value on Axis C in Step 2 by the same factor, to obtain the required quantity for NCO/OH = 1.
Example 2.For the same materials as Example 1:Extend straight line from 23.1 on Axis A through 80 on Axis B to Axis C, and read the value of approx. 26 on Axis C as the DURANATE™ quantity required for this application, in wt. parts per 100 wt. parts polyol.
Example 3.For DURANATE™ E402-90T (NCO = 8.5%), with all other materials as in Examples 1 and 2:Multiply NCO value by two, extend straight line from 17 on Axis A through 80 on Axis B to Axis C, read the value of approx. 35 on Axis C, and multiply by two to obtain the DURANATE™ quantity of 70 wt. parts per 100 wt. parts polyol as the requirement for this application.

In no event will AKCC be responsible for damages of any nature resulting from the use of or reliance on such information or the related product. AKCC makes no representation or warranty, express or implied, that use of any product, process, equipment, or formulation will not conflict with any patent, and nothing contained herein is to be construed as a recommendation for such use.
Always observe all of the following precautions for any DURANATE™ handling, use, or storage.Consult the relevant Material Safety Data Sheet (MSDS), available from Asahi Kasei Chemicals Corporation (AKCC), before handling or using any DURANATE™ grade. The MSDS and the following precautions apply only to DURANATE™ as supplied, and it is the customer’s responsibility to investigate and ascertain the safety and suitability of any materials or equipment and their use with DURANATE™.Do not use DURANATE™ in any application which might involve its contact with medicines, pharmaceuticals, medical devices, food, or drinking water, or any other application which might result in personal injury or health degradation. Consult your DURANATE™ representative or AKCC for further information.
HAZARDS IDENTIFICATION¡Flammable Liquid. Can release vapors that form explosive mixtures at temperatures above flash point.¡Vapors cause irritation of eyes, nose and throat.¡Inhalation may cause toxic symptoms.¡Repeated contact may cause allergic skin reaction.
ATTENTION¡Keep away from flame, spark and other ignition sources at all time.¡Provide thorough ventilation in all areas of use and handling.¡Wear safety goggles and gloves; use respiratory equipment in any area of use or handling that lacks thorough ventilation.
FIRST AID MEASURES¡Inhalation ・Move the victim to the area under fresh air. ・If not breathing, give artificial respiration. ・Call for prompt medical attention as soon as possible.¡Skin contact ・Remove contaminated clothing and shoes. ・Flush affected areas with large amount of water and soap. ・Get medical aid if irritation develops or persists.¡Eye contact ・Immediately flush eyes with plenty of running water for at least 15 minutes, occasionally holding eyelids apart. ・Get medical attention.¡Ingestion Give 2-4 cupfuls of water or milk. ・Get medical aid immediately. ・Never give anything by mouth to an unconscious person.
ACCIDENTAL RELEASE MEASURES¡Wear appropriate personal protective equipment.¡Use bunding or absorption with inert material (e.g. dry sand, earth) to prevent product from entering drains or surface
water.¡Ventilate area of leak or spill. Remove all sources of ignition.¡Evacuate unnecessary and unprotected personnel.¡Contain and recover liquid when possible.¡Collect liquid in an appropriate container or absorb with an inert material.¡Do not flush to sewer.¡For small quantities, wipe off with cloth or paper, and wash with water and detergent. ¡For large quantities, recover by taking up mechanically or with an inert absorbent material such as waste cloth, dry sand, or
earth.¡Wash residue with water and detergent.¡Follow prescribed procedures for responding to larger spills and reporting to appropriate authorities.
HANDLING AND STORAGE¡Handling Workshops should be well ventilated. ・Avoid contact with skin and eyes. Avoid injection and inhalation. ・Avoid contact with heat, sparks and flame. ・Use proper bonding and grounding procedures to reduce potential for static discharge. ・Use spark-proof tools and explosion-proof equipment. ・HDI homopolymer reacts slowly with water to form CO2 gas. ・This gas can cause sealed container to expand and possibly rupture explosively. ・The routine use of neutral or weak acid type of hand cleaner and regular cleaning of working surfaces, gloves, etc. will help minimize the possibility of a skin reaction.¡Storage ・Keep container tightly closed. Store in a cool, dry, well-ventilated area. ・Keep away from sources of ignition.
Contact your DURANATE™ representative or AKCC in the event of question or uncertainty concerning safe storage, handling, and use of DURANATE™.
